  • RPI SCOREC - Technical Reports
    Modification Year 2006 Journal Engineering with Computers Institution Rensselaer Polytechnic Institute Abstract Improvements to a local modification based anisotropic mesh adaptation procedure are presented The first improvement focuses on control of the local operations that modify the mesh to satisfy the given anisotropic mesh metric field The second is the parallelization of the mesh modification procedures to support effective parallel adaptive analysis The resulting procedures are demonstrated on general curved

    use However the traditional reliance on library based implementations of these functionalities hampers experimentation with different software instances that provide similar functionality This is especially true for meshing and geometry libraries where applications often directly access the underlying data structures which can be quite different from implementation to implementation Thus using different libraries interchangeably or interoperably for this functionality has proven difficult at best and has hampered the wide spread

    increasingly sophisticated and rely on advanced meshing and discretization tools Unfortunately it is still difficult to interchange or interoperate tools developed by different communities to experiment with various technologies or to develop new capabilities To address these difficulties we have developed component interfaces designed to support the information flow of mesh based PDE simulations We describe this information flow and discuss typical roles and services provided by the geometry mesh

  • RPI SCOREC - Technical Reports
    Rensselaer Polytechnic Institute Abstract Abstract For the purpose of efficiently supporting parallel mesh based simulations we developed a partition model and a distributed mesh data management system that is able to shape its mesh data structure dynamically based on the user s representational needs to provide the needed representation at a minimum cost memory and time called Flexible distributed Mesh DataBase FMDB The purpose of the partition model is to

    the mesh adaptation procedure to maintain structured and graded elements near the wall resulting in a more accurate wall shear stress computation To perform mesh adaptation for hemodynamic flows a single mesh metric field is constructed for the whole cardiac cycle Two alternative approaches are applied one in which a metric field is constructed based on the average flow whereas in the other approach the metric field is obtained by

    attention It is well known that fcc Fe is thermodynamically unstable at ambient conditions and not ferromagnetic Contrary to what is known in this system we report that elongated nanoparticles of fcc Fe grown within graphitic nanotubes by the vapor phase interaction of ferrocene and hydrocarbons remain structurally stable and appear ferromagnetic at room temperature The magnetic moment 2 0 5 mB in these nanoparticles observed using magnetization measurements and
